Web Survey Bibliography
Online survey experiments with different question forms are frequently employed to evaluate question wordings and response scales. Building on the results of these experiments more accurate wordings and response scales are selected. Yeager et al. (2011) challenged the inconsiderate use of non-probability online samples by showing that different non-probability online samples do not lead to equal conclusions in terms of the distribution of substantive variables. Based on their findings, this paper investigates whether identical split ballot design experiments employed in seven non-probability online surveys reveal equal results.
